"Game of Thrones" Season 5 finale title has been revealed by HBO and it hints at the reappearance of one major character.

One of the popular taglines of "Game of Thrones" says: "All Men Must Die," but it looks like the finale of the ongoing season may see one important character coming back from the dead.

The episode, titled "Mother's Mercy", has sparked speculations that Lady Stoneheart, the resurrected spirit of Catelyn Stark (Michelle Fairley), may make a comeback in the episode.

There are plenty of mothers like Cersei or the Mother of Dragons, Daenerys, that the title could be referring to. But if you've read the book, you will know that there's only one mother who fits the title completely at this point in the story.

According to the appendix of George RR Martin's novel, 'A Feast for Crows', one of Stoneheart's aliases is Mother's Mercy and she is also referred to as "Mother Merciless" in the book, points Huffingtonpost.

As viewers and readers know, Catelyn was murdered at the infamous Red Wedding, which was aired in Season 3's 'The Rains of Castamere' episode. But in a major twist in the book, Lady Stark is brought back from the dead by Beric Dondarrion and the Lord of Light.

Those who have read the books know that Lady Stoneheart is otherwise known as Mother Mercy.

Now, the title is quite a giveaway and points towards an epic ending of the ongoing season, which could also have a big impact on the storyline. But these are only speculations and don't really confirm anything.

Actress Michelle Fairley, who played Catelyn in the show, had confirmed that Lady Stoneheart had been excluded entirely from the HBO series.

But let's just assume that Lady Stoneheart makes a comeback. Then what?

It makes sense because she would not only be taking revenge from the Bolton's for killing her and her son Rob, but will also be saving her daughter Sansa from Ramsay's psychotic wrath.

Well, but since the official synopsis from HBO, which reads "Stannis marches. Dany is surrounded by strangers. Cersei seeks forgiveness. Jon is challenged", doesn't say anything about Lady Stoneheart or her revenge, it's highly likely that the title points to a quote from the High Sparrow.

During the seventh episode, he explained to Cersei that "Mother's Mercy" was something bestowed upon a person who is accused of sinning against the odds.

In the books, Cersei is forced to march through the streets of King's Landing naked so her shame is bare for all to see. We know this scene will appear at some point in Season 5, could it be during the final episode?
